Iced Coffee

It has been ridiculously hot recently and so my normal caffeine fix has been too hot to drink. So I went scouring the internet for a recipe for Iced Coffee (as it is far too expensive to keep my coffee fix in hand by buying iced coffee in Starbucks etc.).

After converting, experimenting and tweaking I have finally settled on a recipe I like. So I thought you might like a copy as well. There is a recipe summary at the end.

To make it you need to start preparations a day in advance. Find a jar or plastic container that can hold a litre of water. I used an EasiYo yoghurt maker jar. Put 70g of coffee grounds in the jar and fill up with about a litre of cold water. Screw the lid on tightly and give it a good shake. Leave this to stand and infuse for about 12 hours.

After 12 hours (or overnight) filter the coffee. I put a coffee filter bag in a sieve balanced over a jug. The carefully put a little coffee at a time through the filter. It took about 20mins to filter all the coffee (and about 6 coffee filter papers). Decant this ‘coffee concentrate’ into a clean jar and store in the fridge.

Now you are ready to make iced coffee.

Put 4oz of coffee concentrate in a pint glass (or jar – if you want to take it travelling! Mine survived a 40min drive in a hot car in a Kilner jar) and top up with 4oz of milk. You can change these quantities, but make sure the coffee and milk are equal. Add some sugar (I normally have one tsp of sugar in my coffee, but found that this needed two). Give it a good stir and add in lots of ice cubes. Drink through a straw.

If you don’t drink too much, then the coffee concentrate should keep in the fridge for a week (or more), but I drank all mine in 2 days!
